From 6e5b990c509777544b790cc8e490965166d04684 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20E=C3=9Fer?= Date: Thu, 11 Jun 2026 13:15:12 +0200 Subject: [PATCH] tools/test/stress2/misc/all.debug.inc: skip undefined variables On my ZFS based systems, no allocations occur with tags "newblk" or "freework". This leads to errors executing the tests that check for memory leaks. Skip the checks if the output of wmstat -m does not contain lines corresponding to those allocations.
